Oh! Stealth!
Why yes! Yes there is!

the Bloom Box... totally self contained... paint that puppy red, scuff it up, put a bunch of empty beer cans on top, slap some Snap-On decals and a Confedrate flag on it, stick it in your garage, fill it with clones, lock it, plug it in, and walk away.
Looks like a big assed tool box.
But it'll cost ya.
I have seen one of these units in person and it is quite a beast.
